Question

Find two consecutive odd integers whose products is 783.let x be the first odd integer. Write an expression for the second odd integer.

Answer 1

first odd integer --- x

2nd odd integer ---- x+2

x(x+2) = 783
x^2 + 2x + 1 = 783 + 1 , I completed the square
(x+1)^2 = 784
x+1 = 28
x = 27

the two odd integers are 27 and 29
